Hi all,

I have an old 2001 txt which seems to be pumping oil out of the crank breather pipe! 

Thats what I have pictured, right, the thicker tube ? In the end of the thicker red tube was this plug

So, tech guys. What is the likely reason it would be pumping oil out and how would one fix it ? 

Thank you for your time.

If you are referring to the clutch centre bolt then no, your bike has a different clutch to a pro

I was hoping it was as simple as re routing the breather hose to a higher position . If I need to dig into the engine what should I be looking for if its not the centre bolt ?

Possible reasons for oil pumping out are

Wrong grade of oil - unsuitable oil can foam and expand

Too much oil - check level

Water in oil - this will be accompanied by discoloured oil - usually turns grey / milky / cloudy

Leak into gearbox from crankcase - porous casting or faulty gasket.

Or a crank seal

Cheers folks. That all gives me something to aim for .

 

Here is another question as im looking at the manuals on line.  

My bike was originally a 250 but somewhere along the line its has either had a 320 head fitted or whole new engine.

Q, Can a 320 head be retro fitted keeping existing lower casing.  I presume the crank etc would be that same anyway on either the 250 or 320?  in which case i would be looking at 250 parts list on the GasGas site ?
